Technics SL-PS860

The compact disk player which carries high-quality sound technologies, such as S-advanced MASH and Class A DAC, and virtual battery operation.

S-advanced MASH and Class A DAC are adopted as a D-A-conversion part. This circuitry is considered as S-advanced MASH and 3LSI stream compositions of two class A PWM output ICs which were adopted from the high order model, and upgrade is aimed at by building a 4th noise shaping circuitry and a digital demphasis circuitry in the conventional advanced MASH. moreover, by 3 chip-ization of LSI, the separation of the PWM output IC of MASH section LSI and each L/R channel is carried out, the influence of a digital noise is avoided, and the stroke between channels is reduced.

Moreover, the PWM output unit was changed into Bipolar from conventional C-MOS, and the occurrence of overshooting on a PWM wave or a under shoot is controlled by reducing an occurrence of the penetration electric current by the abrupt change of the electric current in the changing point of pulse shape. The peak value of the pulse by this was stabilized and the ideal PWM output is realized. Furthermore, the clock Jitter is stopped by arranging a crystal oscillator near the digital analog converter.

The virtual battery operation circuitry is adopted as a power-source part. In this circuitry, the FET element was included in the power circuit, it is a capacitor charge side, the noise of an AC power source and the noise mixed in an audio circuitry from a reference-supply occurrence were intercepted, and it has prevented a noise mixing in a sound signal.

The digital servo was carried and the stable drive is realized by adjusting the amount of servoes according to the status of each one one-sheet disk.

While having adopted the silence mechanism and making a disk tray wide with 140мм, the mechanism is arranged in the good center of a weight balance. Moreover, TNRC by the multilayer structure of a metals and BMC is adopted, and the oscillation from the outside is reduced.

SL1 excellent in silence is adopted as a loading mechanism, and the clearness of a sound is secured by suppressing a mechanism's vibration. Furthermore, the silence operation is realized by adopting an original swing arm drive system.

The class AA circuitry is adopted as a lineout circuitry, and the ideal Class-A operation is realized.

The internal and external oscillation is reduced by THCB (technics hybrid construction base) which acquired the periodic-damping property excellent in combining a steel plate and a viscoelasticity object, and four large-sized insulators. Moreover, the oscillation of a mechanism is controlled by arranging an optical deck mechanism in the good central part of a weight balance, and also carrying out a floating by a double insulator.

The digital optical termination is carried.

The display mode functionality is carried and a display-device window can be switched off.

The line-output termination in which gilding was given is carried.

The synchro edit functionality is carried, by combining with the cassette deck with an exclusive termination of technics/Panasonic, the deck is interlocked with and an edit sound recording can be performed.
